   Einen Eventaufruf einem Objekt zufügen.

   Folgende Parameter werden übergeben:
  

   obj 		- Das Objekt auf dem der Event stattfindet. [Default: window]
   event 	- Der Event der beobachtet werden soll (ohne 'on') [Default: load]
   function 	- Eine Funktionsreferenz


   Die Funktion kann auf 2 Arten benutzt werden. 
   
   addEvent( obj, event, func);
   addEvent( { func: function, evt: event, obj: obj})
